Lift bars 22′ may beattached to members 22 by coping such that lift bar 22′ protrudes withinor into member 22 and lift bar 22′ is welded into place at the junctureof bar 22′ with member 22. A plurality of lift bars 22′ may be engagedby a lifting device such as a crane to lift and move skid 10 as needed.

As shown in FIGS. 1-4, 8 and 10, scaffold 20 may comprise a carryingmanifold 23. Manifold 23 may be affixed to one or more vertical scaffoldmembers 21 or may be supported by an independent support mechanism, notshown. Manifold 23 provides a number of carrying and other functions.Manifold 23 may define one or more substantially lateral channels 24.Channel 24 is configured to carry components of a storage drawer 30 suchas rollers 32 disposed on drawer 30 to facilitate lateral movement ofdrawer 30 in and out along channel 24.

Manifold 23 may further comprise one or more sloped members 25. Slopedmember 25 may carry an overlying tank, such as tank 40 discussed below.The angle of sloped member 25 is configured to substantially correspondto a sloped bottom wall 45 of tank 40. Manifold 23 may further defineone or more pockets 26 configured to receive a fork of a forklift forlifting and moving skid 10. The portion of manifold 23 defining theupper horizontal portion 26′ of pocket 26 may also carries tank 40.

Manifold members 27 may also define a trough cavity 29, see FIG. 2.Upwardly extending manifold members 28 define lateral supports for tank40. For example, in one embodiment tank 40 and/or tank 50 may furthercomprise sides walls to which upwardly extending manifold members 28 maybe connected for attachment. In the alternative, the position occupiedby tank 40 could be shared and occupied by two tanks side-by side.

Manifold 23 may be constructed by joining a number of shaped portionstogether. In the alternative, manifold 23 may be formed by an extrusionprocess. Scaffold 20 may be constructed of aluminum, steel, or othermetal or composite materials, or a combination of aluminum, steel, othermetal and/or composite materials depending on the desired weight of lubeskid 10 and/or on the carrying strength required of components ofscaffold 20.

As shown in FIGS. 3 and 4, lube skid 10 may further comprise one or moreservice storage drawers 30. FIG. 3 is a front view of skid 10. FIG. 4 isa rear view of skid 10.

Tank 40, ormultiple tanks, may serve as a waste receptable to receive fouled, usedand/or waste fluid evacuated from the vehicle or equipment servicedusing skid 10 or from sump 60.

As illustrated in FIG. 4, in one embodiment tank 40 is positioned abovemanifold 23, or its equivalent, so that tank 40 is carried by manifold23. Thus, the bottom wall of tank 40 may be configured to substantiallycorrespond with the underlying portion of manifold 23. In this way theweight of tank 40 is distributed over scaffold 20. For example, tank 40may comprise a sloping bottom wall portion corresponding to manifoldmember 25. Further, bottom wall of tank 40 may also conform to manifoldmembers 27 to create a corresponding trough 29, see FIGS. 4 and 5A,within tank 40. Trough 29 within tank 40 defines a lowest area withintank 40. Sloped bottom walls of tank 40 serve to assist gravity toaccumulate any remaining waste fluid in tank 40 to trough 29 within tank40. Drainage or suction hardware (not shown) may be used to remove wastefluids from tank 40. Drainage hardware may be placed within tank 40 andattached at or near the lowest portion of tank 40 in trough 29. Drainagehardware may be attached on a rear wall 43 of tank 40. In this way, upondraining waste fluid from tank 40 the amount of residual waste fluidleft in tank 40 is minimized.

If desired, tank 40 could be partitioned into two receptacles forreceiving different waste fluid. The location of a partition in tank 40could be selected to configure at least a portion of each partitionedreceptable to include a similarly functioning trough. Separate drainagehardware for each of the partitioned receptacles could be installed inin the lowest areas of each receptacle to drain waste fluid from eachpartitioned receptable. Or, separate drainage hardware for eachpartitioned receptable may be attached on rear wall 43 of tank 40 thecorresponding trough. In this way, upon draining waste fluid from eachpartitioned receptable the amount of residual waste fluid left in eitherreceptable is minimized.

This sloped configuration of bottom wall 55 defines a lowest areawithin tank 50 to which product accumulates under gravity and from whichproduct may be pumped and/or from which product may be drained from tank50. Drainage hardware (not shown) may be used to remove product fromtank 50. Drainage hardware may be attached at or near the lowest portionof tank 50. For example, drainage hardware may be attached on a rearwall 53 of tank 50. This kind of sloped configuration of bottom wall 55minimizes the amount of residual product left in tank 50 after pumpingor draining. Sloped bottom wall 55 also accommodates stacking of tank 40on tank 50 and provides a substantially even distribution of the weightof tank 50 upon tank 40 and scaffold 20. As shown in FIG. 5, top wall 52of tank 50 may also be sloped creating a rhombus cross-section of tank50. As shown in FIG. 9 and other Figures, tank 50 may further comprise afill port 56 through which product may be pumped or poured into tank 50.
